What is Digital Signage?

Digital signage refers to the use of digital displays to broadcast messages or advertisements. Unlike traditional static signage, it uses computer monitors, LCD screens, plasma displays, or projections to display content such as advertisements, directions, menus, emergency information, and other messages. The content displayed is generally connected to a content management system that allows users to remotely update the screens easily and efficiently.

Hardware Components
A basic system consists of three main hardware components - a display device, a media player, and content management software. The display device is the screen used to present the Digital Signage content. Popular display options include LCD, LED, and projection screens in various sizes. The media player is responsible for receiving content from the CMS and displaying it on the screen. Typical media players connect to displays through HDMI or DVI ports and range from dedicated appliances to mini PCs. The content management software allows users to create, schedule, and distribute content to one or multiple screens from a central location.

Content Delivery
Digital signage content delivery involves distributing files like images, video, and other rich media assets from the CMS to each display device. Common delivery methods include network/wired connections using Ethernet, Wi-Fi networks for wireless delivery, or external storage devices like USB drives. Advanced systems also offer content delivery over the internet through cloud-based models. Users can schedule playback of content on precise display schedules, control messaging based on triggers like time of day, location, weather, etc. Real-time data feeds can also dynamically update signage content.
